The incidence of wireless network problems with data quality has declined driven primarily by network upgrades and increased network capacity through an expansion of 4G service coverage according to J.D. Power.

Data quality has been the primary driver of the improvement in wireless
network quality during the past three years. Total data quality problems have
declined to 14 PP100 in 2014 from 19 PP100 in 2012.

Both data speed and connectivity improve this year. Issues related to slow
mobile Web experiences have declined to 17 PP100 in 2014 from 21 PP100 in 2012,
which is largely attributed to broader rollouts of 4G networks. Similarly,
issues with email connections have declined to 5 PP100 from 7 PP100 during the
same time frame.

This increasingly positive experience with their network is translating into
increased engagement for wireless customers. For example, 25 percent of
customers using 4G smartphones say they "strongly agree" that they are
committed to their carrier, compared with 20 percent of those using 3G
smartphones who say the same.

Customers using faster, more efficient 4G networks are 14 percent more likely
to recommend their wireless carrier than those using networks that have not yet
been upgraded.

"While the performance of network data quality has improved, given the
robust upgrade to 4G technology across the country, there is still performance
disparity across user segments and type of devices," said Kirk Parsons,
senior director of wireless services at J.D. Power. "Based on the varying
degree of consistency with overall network performance, it's critical that
wireless carriers continue to invest in improving both the call quality and
especially the data connection-related issues that customers continue to
experience as 4G service becomes even more prevalent."
